This paper presents a model based on game theory, for the characters of the evacuation behavior in emergency. In consideration of evacuees’ interact during the evacuation process, every evacuee makes a best decision due to others’ strategies, which is called Nash equilibrium strategy. This model presents a Method for solving the Nash equilibrium, and the rationality of the method is validated by sample simulation. The model simulates the process of the evacuation by adopting cellular automata technology to indicates the model can simulate effectively the personnel emergent characteristic under the multi-exits condition.
